Circle Theorems I
Bayani Gaba-gaba
Circle theorems are elegant rules about the angles inside a circle. Used together they let you find angles that would otherwise be out of reach, and they reward clear step-by-step reasoning.
In this lesson you will calculate angles using circle properties: the angle in a semicircle and the tangent-radius right angle (Core), plus (at Extended) the angle at the centre, angles in the same segment, cyclic quadrilaterals and the alternate segment theorem.
Manufura
- Calculate unknown angles and give explanations using the following geometrical properties of circles: angle in a semicircle = 90° angle between tangent and radius = 90°.
- Calculate unknown angles and give explanations using the following geometrical properties of circles: angle in a semicircle = 90° angle between tangent and radius = 90° angle at the centre is twice the angle at the circumference angles in the same segment are equal opposite angles of a cyclic quadrilateral sum to 180° (supplementary) alternate segment theorem.
